9FGV0231
2-Output Very Low Power PCIe Gen1-2-3 Clock Generator
The 9FGV0231 is a 2-output very low power clock generator for PCIe Gen 1, 2 and 3 applications. The device has 2 output enables for clock management and supports 2 different spread spectrum levels in addition to spread off.
Features
- 1.8V operation: reduced power consumption
- OE# pins: support DIF power management
- LP-HCSL differential clock outputs: reduced power and board space
- Programmable Slew rate for each output: allows tuning for various line lengths.
- Programmable output amplitude: allows tuning for various application environments.
- DIF outputs blocked until PLL is locked: clean system start-up
- Selectable 0%, -0.25% or -0.5% spread on DIF outputs: reduces EMI
- External 25MHz crystal: supports tight ppm with 0 ppm synthesis error.
- Configuration can be accomplished with strapping pins: SMBus interface not required for device control.
- 3.3V tolerant SMBus interface works with legacy controllers.
- Space saving 24-pin 4x4 mm MLF: minimal board space
